I am attempting to get a BLE mesh network running using the BLE mesh sensor examples. I have one nRF52840 board and multiple Fanstel EVM-BC833 nRF52833 based boards. I have tried running both client and server examples on both boards with similar results so I must have a configuration issue. When I run the server example on the nRF52840 board and go through the provisioning the board, it reboots due to an MPU fault (see below). When I run the same example on the nRF52833 Fanstel board it continuously reboots (see below). I first load the S140 softdevice image using the programmer and then I use VS Code to program the example. I have not modified the board configuration for the nRF52840 and have created a board configuration for the Fanstel EVM using the nRF52833 eval board configuration as a template.
